IMPROVEMENT IN OATMEAL-MACHINES.

Specification forming part of Letters Patent No. 170,745, dated December7, 1875; application led September 11,1875.

To all whom 'it may concern:

Be it known that I, HENRY KRUsE, of the city of Akron, Summit county,Ohio, have invented an Improvement in Oatmeal-Machines,

-of which the following is a specification:

My invention relates to that class of oatmeal-machines wherein a hopperhaving a perforated metallic bottom slides upon a series of horizontalknives, so arranged that the kernels of grain falling endwise throughthe `bottom of the hopper shall be sheared ofi' by the knives as thehopper slides across them.

The object of my invention is to render the particles of meal uhiform insize, and insure the cutting of each kernel of grain. I accomplish thisby using single-edged knives, arranged so closely together that kernelsof oats cannot fall vertically between them, and beveling the upper sideof these knives toward the back, so that the blade shall form a stop,against which the ends of the kernels of oats falling through theperforated bottom of the hopper shall strike and be arrested until cutoff by the following knife, when the severed pieces fall over the bae'kedge of the knife into a proper receptacle below.

In the accompanying drawing, Figure 2 is a perspective view of anoatmeal-machine embodying my invention; and Fig. l, a crosssection of aportion of the perforated plate C and knives D, to show the arrangementan construction thereof.

In Fig. 2, B' is the hopper, with the perforated bottom C, moved by thepitlnan AF, crank E, and pulley G, and sliding in the frame A on theknives D D, Sto. These knives are beveled toward the back, as shown inFig. l, so that a space is left between them and the plate C, whichregulates the size of the particles of grain out off, as shown at C,Fig. 1. These knives may be placed in an independent sliding frame, ifdesired, so as to move in an opposite direction to the plate O. Byfastening these knives by pivots o r journals at the front edge the backcould be raised and lowered, so as to regulate the size of the particlesof meal at will.

I claim as my invention- In an oatmeal-machine, the beveled knives D D,applied, as set forth, in relation to plate (l, serving both to cut thegrain and as a gage to regulate the size of the particles of meal,substantially as described.
